I need shell_exec(): to remove it because I installed it through Fant, but Fant being the way it is, it requires me to prepare it for removal first, which requires shell_exec(); to be on.
Even if I do delete the folders, I won't be able to install any other cms through Fant, because it hasn't been removed from the Fant registry, which, I can't do for some reason. Download installs aren't an option for me, because I'm on dialup.
